Metal 'scar' discovered on cannibal star: Study
Metal ’scar’ discovered on cannibal star: Study
Western researcher part of team that found a unique signature of a star ingesting surrounding planets and asteroids When a star like our Sun reaches the end of its life, it can expand to ingest the surrounding planets and asteroids that were born with it. Using the European Southern Observatory's Very Large Telescope (ESO's VLT) in Chile, researchers, including Western physics and astronomy professor emeritus John Landstreet , have found a unique signature of this process for the first time, a scar imprinted on the surface of a white dwarf star.

Destruction of an Earth oceans' worth of water per month in Orion Nebula
Destruction of an Earth oceans’ worth of water per month in Orion Nebula
An international team, including Western astrophysicists Els Peeters and Jan Cami , has shed light on the destruction and re-formation of a large quantity of water in a planet-forming disk located at the heart of the Orion Nebula. This discovery was made possible by an original multidisciplinary approach combining observations from the James Webb Space Telescope (JWST) and quantum physics calculations.

Children in marginalized communities more likely to experience cardiac arrests
Western study finds children in marginalized communities more likely to experience cardiac arrests A new study shows children living in marginalized communities are at a higher risk of experiencing paediatric out-of-hospital cardiac arrest (POHCA) - a rare, life-threatening event occurring outside a hospital setting in which a child's heart suddenly stops beating.

New technique can quickly detect fentanyl and other opioids
Testing method can analyze blood samples twice as quickly as other techniques University of Waterloo researchers have developed a new blood testing method that can detect potent opioids much faster than traditional approaches and potentially save lives. The method, the latest effort by Waterloo researchers and entrepreneurs to lead health innovation in Canada, can simultaneously analyze 96 blood samples that could contain opioids such as fentanyl in under three minutes - twice as quickly as other techniques.

Fighting the flu: The surprising power of a century-old vaccine for tuberculosis
As Canada's flu season collides with record strep A cases and ongoing COVID-19 concerns, a new study is shedding light on our understanding of respiratory immune responses. Scholars from the Research Institute of the McGill University Health Centre (RI-MUHC) have discovered a surprising facet about a century-old vaccine for tuberculosis, Bacillus Calmette Guérin (BCG).

Researchers are using RNA in a new approach to fight HIV
Society learned about the value of mRNA during the COVID-19 pandemic when we saw scientists and medical professionals harness its power to deliver a vaccine for the virus within a year. Now, University of Waterloo pharmacy associate professor Emmanuel Ho has developed a novel nanomedicine loaded with genetic material called small interfering RNAs (siRNA) to fight human immunodeficiency virus (HIV) using gene therapy.

Lessons from the pandemic: the trouble with working from home
Researchers in Canada and France followed 700 office workers for six months in 2020 and 2021 to see how they were coping. Their findings reveal a less than favorable outlook on extensive remote work. Remember when COVID-19 hit, and suddenly everyone was working from home? Well, a team of researchers in Montreal and Paris decided to dig deeper into how this shift affected office workers during the pandemic.

Energy poverty in Canada
As many as one in five Canadian households can be considered to be in energy poverty, according to researchers from McGill University. Energy poverty occurs when households cannot afford or access the levels of energy necessary to meet their daily needs, live decent lives, and maintain healthy indoor temperatures all'year round.

How the brain develops in unborn babies
An UdeM-led study reveals the combined effect of genetics and food availability, and points the way forward to promoting cortical growth after birth in small babies. Postdoctoral fellow Daniel Vosberg and CHU Sainte-Justine researcher and Université de Montréal medical professor Tomas Paus Credit: Véronique Lavoie, CHU Sainte-Justine A new population-based study led by CHU Sainte-Justine researcher and Université de Montréal medical professor Tomas Paus reveals the roles of maternal and fetal genes in the growth of a baby's cerebral cortex.

Stress is higher for women in long-term relationships
Stress is higher for women in long-term relationships
In long-time couples, women are more affected than men by the cumulative effects of stress as measured by the physiological indicator known as allostatic load, a U.S.-Canada study suggests. The chronic stress that builds up over decades in a relationship affects each member of the couple differently; in heterosexual couples, the woman is more likely to display negative physiological markers than her spouse.

Uncertainty in measuring biodiversity change could hinder progress towards global targets for nature
Uncertainty in measuring biodiversity change could hinder progress towards global targets for nature
Researchers find it could be difficult to detect biodiversity improvements due to conservation action for nature and suggest practical solutions to guide conservation More than ever before, there is a growing interest in dedicating resources to stop the loss of biodiversity, as recently exemplified by the Kunming-Montreal Global Biodiversity Framework (GBF) decided at COP15 in December 2022.

Can smells improve your athletic performance?
Yes, they can, says Mathieu Cournoyer, a master's student in human kinetics who's done a review of 19 studies on the topic. Did you know that the scent of peppermint can make you run faster? That a whiff of ammonia will make you do a few more push-ups than usual? Or that the fragrance of jasmine can improve your bowling score? Those and other findings were made by Mathieu Cournoyer, a master's student in UdeM's School of Kinesiology and Human Kinetics, who reviewed 19 studies on the effect of olfactory stimulation on physical activity.

How parents can help prevent the development of ADHD symptoms
ADHD can be stemmed through specific parenting behaviours Parents of young children with an excitable or exuberant temperament could adapt their parenting style to help moderate their child's potential development of Attention Deficit/Hyperactivity Disorder (ADHD), according to a new study co-authored by a University of Waterloo researcher.

Saturn's largest moon most likely non-habitable
Saturn’s largest moon most likely non-habitable
A study led by astrobiologist Catherine Neish for Western University shows the subsurface ocean of Titan - the largest moon of Saturn - is most likely a non-habitable environment, meaning any hope of finding life in the icy world is dead in the water. This discovery means it is far less likely that space scientists and astronauts will ever find life in the outer solar system, home to the four 'giant' planets: Jupiter, Saturn, Uranus and Neptune.

Western researchers examine intimate relationships  
Valentine's Day means the stores are filled with hearts and chocolate and florists are rushing to fill orders. But beyond cards and candy, what factors make for a strong relationship that lasts?  Why do some relationships break down and others flourish? How does a relationship progress to a long-term partnership? How important is sexual compatibility in a successful relationship?  These are among the questions researchers in Western's psychology department are examining, through relationship studies involving feedback from couples in intimate relationships.
